extension
what joint is this?
what type of joint is it?
Coxae joint – Hip joint
ball-and-socket or spheroidal joint
Spheroidal joint of the hip joint is formed between what 2 structure
lunate surface of the acetabulum
head of the femur
what ligament is the red arrow pointing ot
what ligament is the blue arrow pointing to
red: Ligament of the
head of the femur
(acetabular fossa – fovea of the femoral head)
blue: Transverse acetabular ligament
Label 1-3 of the coxal joint
- Ligament of the head of the femur
(Is intracapsular but not intraraticular) - capsule of hip joint
- synovial membrane of hip joint
How would you describe 1 compared to normal
Dysplastic
How would you describe 2 compared to normal

what is this showing
Severe signs of osteoarthritis or arthrosis
Drawer sign/test in stifle joint test for?
Rupture of cranial cruciate ligament
what ligament is this
Caudal cruciate ligament
what ligament is this

Femoropatellar (hinge)
Femorotibial (condylar)
Proximal tibiofibular (plane)
what joint is this
Genual joint (Stifle)
what ligament is the blue arrow pointing to
Patellar ligament
Correspond to the quadriceps femoris Tendon. Inserts in the
Tibial tuberosity
what is the blue arrow pointing to
what does it do
Lateral & medial femoropatellar ligg
Attach the patella with the lateral and medial fabellae
Femoropatellar joint is what type of joint
synovial-hinge
Caudal cruciate lig. Prevents (2):
-caudal displacement of the tibia against the femur
-lateral rotation of the joint
Cranial cruciate lig Prevents
-cranial displacement of the tibia against the femur
-hyperextension of the genual joint
-medial rotation of the joint

- Extend proximal to the patella.
Between the quadriceps and
the femur - Include the fabellas and the
Proximal tibiofibular joints - Collateral ligg. and popliteal tendon
Are extracapsular structures. - Form a tendon sheath for the long digital extensor m. tendon.
